Adjust qcc_emit_cc_app() to allow the delay of emission of a CONNECTION_CLOSE. This will only set the error code but the quic-conn layer is not flagged for immediate close. The quic-conn will be responsible to shut the connection when deemed suitable. This change will allow to implement application graceful shutdown, such as HTTP/3 with GOAWAY emission. This will allow to emit closing frames on MUX release. Once all work is done at the lower layer, the quic-conn should emit a CONNECTION_CLOSE with the registered error code.
